I've never been one to believe that comfort food has to be rich and fattening to be satisfying. Usually, for me at least, it's all about the memories that food evokes.

I get just as excited about a salad of curly endive dressed with red wine vinegar and lots of garlic as I do about a homemade cavatelli covered in a thick marinara.But there are days when I want something that will make me feel good, at least when I'm eating it, even though I know the guilt will come soon enough.This macaroni and cheese is loaded with guilt, but it's so good, you're going to want to eat it anyway. The good thing is that it's so rich, it fills you up pretty quickly.I recommend using shell macaroni instead of the usual elbows, as it will hold that thick, creamy sauce.This recipe is adapted from one I've used before. I took it from a simple, rich dish to a decadently delicious macaroni and cheese, loaded with a variety of flavors that all complement one another. It's good.If you're having a bad day, and looking for a little comfort, this might be just what you need.Decadently Delicious Mac & Cheese3 cups uncooked shell macaroniOne-half cup onion, diced4 pieces of bacon, dicedOne-half cup butterOne-half cup flour1 and one-half cups milk1 cup sour cream8 ounces Velveeta cheeseOne-half cup grated Romano cheese2 cups shredded cheddarOne-half teaspoon saltOne-half teaspoon pepper1 teaspoon dry ground mustardOne-quarter teaspoon cayenne pepper1 cup diced cooked ham2 cups frozen peas, rinsed in warm water and drainedCook macaroni according to directions on box.In a skillet, cook onion and bacon until onion is soft and bacon is cooked through.
